DXW21BN7511TL08

Balun Overview

The DXW21BN7511TL08 is a surface-mount balun transformer from Murata Electronics, designed for RF applications. It operates within a frequency range of 50 MHz to 1.8 GHz and supports a maximum DC voltage of 20V. The component features an unbalanced impedance of 75 Ohms and a balanced impedance of 75 Ohms, with a maximum insertion loss of 1 dB. It has a four-pin configuration in a 0805 (2.0mm x 1.2mm x 1.2mm) package. The device functions reliably between -40°C and +85°C, complies with RoHS standards, and exhibits a maximum DC resistance of 770 mOhms.

Balun Feature Summary

• Converts single-ended signals to differential signals across a wide bandwidth up to 1.8 GHz
• Compact 0805 surface-mount footprint suitable for space-constrained designs
• Low insertion loss ensures efficient signal transmission
• RoHS compliant construction for environmental safety

Balun Applications

• RF front-end modules in wireless communication devices
• Balancing circuits for audio and signal transformers
• Impedance matching in broadband RF systems

Balun Procurement Notes

Verify the specific suffix TL08 against official Murata documentation to confirm pinout and electrical characteristics, as suffixes may indicate variations in packaging or specifications. Ensure compatibility with your PCB layout regarding the 0805 footprint dimensions. Cross-reference datasheets for thermal limits and impedance tolerances before finalizing procurement decisions.

Balun Selection Notes

Select this component when a 75-ohm to 75-ohm conversion is required in a compact form factor. It is suitable for applications needing operation up to 1.8 GHz with low insertion loss. Consider the 0805 package size for assembly constraints and verify that the operating temperature range meets your system requirements.

Balun Part Context

This part belongs to the DXW21BN series of microchip transformers manufactured by Murata Electronics. These components are wire-wound baluns designed for high-frequency signal processing. The series is characterized by its small size and ability to handle RF signals efficiently in consumer electronics and communication equipment.

Balun Replacement Considerations

Check for equivalent parts such as DXW21BN7511SL if different packaging is needed. Verify that any substitute maintains the 75/75 ohm impedance ratio and covers the 50 MHz to 1.8 GHz frequency range. Ensure physical dimensions match the 0805 footprint for direct replacement.
